'0 (IZZ rz1710/11 it may col/fern Be it known that l. HARRY F. JOSEPH,

citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa. have invented certain new and useful Improvements in l `loo1Cleansing Apparatus. of which the following is a specification, reference being had to the accom panying drawings.

T his invention relates to scrubbing machines and is designed with the primary object in view of providing a machine which is capable of thoroughly and rapidly scrubbing and drying a large ioor space such for instance, as those. usually found in halls and other large auditoriums.

' The invention has for a further object to provide a machine for the above. purpose including a plurality7 of oscillating scrubbing brushes. water supply means for the brushes carried by the machine. a mop oper-V ating in the rear of the brushes to dry the tioor, and means automatically actuated from the handle bars of the machine by which it is propelled to engage or disengage the brushes with or from the tioor surface and simultaneously lower or raise the mop to its operative or inoperative position.

'The invention has fo a more particular object to provide simple. novel and effective means for ilnparting a rotary oscillating movement to the scrubbing brushes as the machine is moved over the floor,

The invention further contemplates the provision of a mopping device including an endless mopping cloth or web. operating means for said web removably mounted in the main frame of the machine and including a roller having frictional engagement with the tioor surface, means controlled from the handle bars for vieldingly holding the lower stretch of the mopping web 1n engagement with the Hoor surface. and additional means operable when the handle bars are released to elevate the mop and its frame out of cooperative relation with said fric-- tion roller.

The invention has for still another object to provide novel means wherel'rv the endless mop may be easily and quickly removed and a new one placed in position when necessary.

Serial No. 812,744.

A further object of the invention resides 1n the provlslon ot water supply means for the scrubbing brushes including a tank and f hose extending therefrom to the brushes, cutoff valves to control the water supply. and connections between the Valves and the handles of the machine whereby pressure against the handle to propel the machine opens the valves and the release of said handles automatically closes said v alves and cuts off the water supply.

The invention has for still another object to generally improve the construction of machines ofthe above character whereby their utility and serviceability in actual use is greatly enhanced without complicating the construction to any material extent 0r increasing the manufacturing cost.

lVith the above and other objects in view as will. become apparent as the description proceeds, the invention consists in certain constructions, combinations and arrangements of the parts that I shall hereinafter fully describe and claim.

For a full umlerstamling of the invention, reference is to bc had to the following description and accompanying drawings. in whicii- A Figure 1 is a side elevation of a combined scrubbing and mopping machine constructed in accordance with the preferred embodi ment'of the invention; Fig. Eis a similar view illustrating the inoperative positions of the scrubbing brushes and mop when the handle bars of the machine are released; the brushes being shown in their elevated positions in dotted lines; Fig. 3 is a top plan view; Fig. Jr is a section taken on the line tHlof Fig. Fig. 5 is a section taken on the line of Fig. 3: Fig. t3 is a sect-ion taken on the line t3 t of Fig. 1: Fig. 7 is a section taken on the line T-T of Fig. l; Fig. S is a section taken on'the line SMS of Fig. l: Fig. 9 is a section taken on the line 9 4) of Fig. 2: Fig. 10 is a` section taken on the line 10-l0 of Fig. 3; Fig. 11 is a section taken on the line 11-11 of Fig. 2; Fig. 12 is a section taken on the line 12-12 of Fig. l; Fig. 13 is an enlarged fragmentary elevation illustrating thearrangement of the lifting roller; Fig. 1J: is a detail section taken on the line 14-14 of Fig. 4; Fig. 15 is a sec-` l. tion taken on the line 15-15 of Fig. 9.

Referring in det'ailto the drawings, 5 designates the two s1m1lar side members of the main frame which includes the obliquelyv disposed bars 6, the plat-es 7 secured. upon the forward ends of said bars and the bearing members 8 whichare secured to theprear ends of the bars 6. These bearing members are loosely mounted upon the shaft 9 upon which the tank or reservoir 10 is secured,

provision being made in the construction of the tank for the accommodation of the drive wheel 11 centrallyxjournaled upon the shaft 9. The main frame of the machine further includes a substantially U shaped bar `12, the ends of which extend rearwardly and vare provided with suitable bearings 13 for the ends of thc shaft. 9. To the arms of this U shaped frame, the handle bars indicated at 14 are connected, the lower ends of said 'bars being connected by a transyerse brace bar.

The plates 7 frame' bars (hare connected by the trans`- versely disposed rod or shaft 15 and upon the same, the rear curved ends of the l'ongi tudinally extending bars 1G are loosely mounted. lThese bars extend"y forwardly in parallel relation ,and uponttllieir Yforward ends,` the bearing members B17 are secured.y Inthese bearing members, the vertical axles 1S of the rotary oscillating brushes generally indicated by the numeral 19 are mounton the forward ends of the bars 81 is pivotally connected to the rear end of one of the levers 29 While the inner ends of said link bars are similarly connected to the slide block 35 mounted between suitable guides 36 provided upon the support 30.

" For purposes which Willmore fully appear from the following description, the support 30 is longitudinally adjustable upon the bars 16 and is secured in its adjusted position by suitable bolts indicated at 37. In

order to compensate for unevenness in the floor surface and wear upon the bristlesof the brushes, I provide upon the under side of the support 30, and centrally thereof, an annular interiorly threaded flange 38. A sleeve 39 is threaded in this annular flange,

said sleeve being closed at on'e end and provided with alstud or pin 40 centrally thereof.

411 indicates the bearing for a wheel or caster 42, said bearing being provided With a hollow cylindrical body 43 toy house a coiled spring 44 arranged upon the pin 40.

This pin is adapted to project through the 1 l end wall of said housing between the arms of thebearing member -41 andis equipped with a suitable head 45. It will be understood ,fronl this construction, that the roller 42 is normally forced downwardly lby the spring 44 into contact with the floor surface as the machine is propelled over the same. By simply adjusting the sleeve 39 within the threaded flange 3S, the normal height at which the support 30 is disposed v above the floor surface may be lregulated as ed. Each of these brushes includes a body i 20 preferably constructed of wood to which the axle 1S is centrally Asecured by means of asuitable screw or bolt 21. As illustrated in Fig. 3 of the drawings, the brush body 20 is of star-shaped form-in plan and cach of" the. radial' extensions thereof is provided with a longitudinal groove or channel 22 into which a bary 23 in which the brush bristics are fixed in any approved manner, is adapted to be inserted.- These bars are securely held in the {rooves of the brush body ag'ainst,longitudinal movement by means of the fastening screws 25. To the upper surface-of the body 20 of each brush, a wear plate 26 issecured for engagement with the bearing member 17. The upper end o1" each brush axle 1S is provided with an arm 27 having a pin 2S formed upon its outer end. 'llo this pin, the forward end of a lever 29 is loosely connected.

30 designates a support upon which link bars indicated at 31 are mounted, one of said link bars being arranged upon each side of the center of said support. Flach of the links is formed with a. thickened central portion having an elongated slot 32 therein. lllithin each of these slots a block 33 is disposed, said blocks being pivoted upon the circumstances and .wear upon the brush bristles may indicate to be necessary. The extent of rotary oscillating movement of the brushes 19, may bc easily and quickly changed or varied as desired b v simply adjusting the support 30 longitudinally upon the frame bai-S16.

rlhe connecting rod 46 has its forward end i pivotally connected to the side block 35, and the rear end terminates in a hook 4G for engagement with the pin 47. mounted upon one end of a crank arm 48, said arm being suitably secured to one face of a pinion 49. The pin'47 is provided with areduced screw threaded portion to receive a suitable nut 5() whereby the connecting rod may be readily removed from the crank arm or connected thereto. The pinion 49 is suitably journaled upon the bearing supsupport 30 by means of the vertical bolts or pins The outer end of each of the link As this block is actuated, the links 31 are moved together upon the pins 31, and

the levers 29 connected to the crank arms Q7 operate to impart a rotary oscillating movement in opposite dlrections to the brushes 19. I By providing one of the links 31 in each pair with a slot for sliding movement upon the otherlink, a maximum movement of the levers 29 may be obtained with a minimum sliding movement of the block 35. The brushes are so mounted that the arms of one brush move into the spaces between the arms of the other brush when the brushes are rotated. Thus every portion of, the floor surface over which the machine 1s moved will be engaged and scrubbed by the brush bristles.

vater is supplied to the brushes slightly in advance thereof by means of the flexible hose indicated at 53 said hose being connected to the water supply tank or reservoir 10. Suitable valves indicated at 5l control the supply of water to the brushes and are automatically opened and closed by means of the rods 5l which connect the arms of the valve plugs with the U shaped bar 12 of the frame, in the manner which will be hereinafter more fully explained.

In conjunction with the scrubbing brushes, I employ an endless traveling mop, the same being constructed and arranged in the following manner: Two similar frame plates 56 are employed in which the ends of a roller shaft 57 are journaled. Upon this shaft the roller 5S constructed of wood is secured. Each of the frame plates 5G is provided with a laterally projecting stud 59 which is adapted tobe received in a slot G() provided in the upper edge of the frame plate 7.

In order to compensate for wear of vthe` traveling mop, and to regulate the pressure of the same upon the floor surface, I provide the adjustable bearing elements indicated at 59 which'are pivoted at one of their ends as at 59 upon the plates 7. T he other ends of these bearing members prof ject inwardly and arevprovided with adjusting screws 59" which are adapted to bear upon the upper edges of the plates 7. It will be noted that the members 59 are longitudinali)y curved and by adjusting the same, they may be raised or lowered with respect to the lower ends of the slots (30. Upon these adjustable. bearings, the studs 59 of the mop frame are supported.

IIpon the forward lower portion of each of the plates 56, a rectangular metal housing or easing G1 is pivotally mounted at one of its ends as indicated at (11. 'ithin this casing a rod (3'.) is movably mounted. This rod is provided with a reduced portion upon which a springll is arranged within the casing. said spring at one of its ends bearing against the shoulder (3i-5 formed upon the rod by reducing the same and at its other end against one of the end walls of the casing. A nut G5 is threaded upon the reduced end of said rod. The forward end of each of the rods 62 is notched as at GG to provide bearings for the -trunnions 67 upon the ends of a roller (i7. A spring held check rod 101 is also mountedupon each of the plates 5G said rods bearing upon theforward ends of the casing 61 and acting to force the roller (37 downwardly.

To the lower edge of each plate 5G Vand projecting inwardly therefrom, a spring clip 105 is secured, said. clips extending beneath the forward ends of the, casings or housings (51 and serving to support the same when the forward ends of the frame plates are elevated .in the manner t0 be later described.

' (3S designates an endless mop constructed of feltor any other desired material which traverses the rollers 5S and 67. The lower stretch of this mop is disposed in a horizontal plane and is adapted for movement over the Hoor surface, said lower vstretch of lthe mop moving forwardly, and tending to carry the water collected in -front of the mop upwardly and rearwardly where Asuitable means is provided which acts by compression to extract the water from the mop. r-Ihis means includes a roller G9 which is mounted at its ends in the metal blocks 70 see Fie. These blocks are irovided s l with tongues 71 which are dove-tailed for sliding movement in the grooves 72 provided in the frame plates 56. rl`his block is prov-ided with an inwardly extending arm 73 for engagement with a trunnion on the end of the compressor roller G9.

Upon the body of the block a hollow member 71 is mounted, through which a rod 75 extends, said rod also extending through the arm 73 and having a nut 7G threaded upon its upper end.-

A spring 77 is arranged within the hollow member 71 and bears against one end thereof, the other end of said spring engaging a suitable head formed in the lower end ofl the rod 75. It will be apparent that by simply 'adjusting the nuts 7G.V the tension of these springs and consequently the pressure of the roller G9 upon the web of the mop GS may' be lregulated.

In order to disengage the bearing arms 73 ,of the blocks 7() from the trunnions of the roller (59, I provide the levers 7S which are fulcrumed at one of their ends upon the respective frame plates 5() as indicated at 79. To each of these levers, intermediate of its ends. one endeof a link SOis pivotally oonn'ected` the other ends of said links being loosely mounted upon the pins S1 formed upon the members 7l having movement in the slots S2 provided in the frame plates 5G. By simply moving the levers 78 in the proper direction, the bearing arms '73 of ioo the blocks 70 Will be moved upwardly out of contact with the roller trunnions so that said roller may bejemoved. In order to position the mop 68 upon the rollers 58 and 67 or remove the saine therefrom, the roller 67 is forced rearwardly against the action of the springs 6-l, and the endless mop web moved transversely of the machine over one of the frame plates 56. Upon the release of the roller 67,-y the springs 64; force the same outwardlyiand stretch the mop web or tightly engage the same upon the peripheries of the rollers 67 and 58.

A trough 88 is mounted between the frame plates 7 and is adapted to receive the water pressed from the'traveling mop by the roller 69. This trough is suitably mounted at its ends upoirthe frame plates 56 and extends transversely between the upper and lower stretches of the mop 68.4 A tube or hose 825 is suitably connected to each end of said 4trough and extends rearwardly therefrom, the other open end of said tube being connected to or disposed above the pan 8l and discharging into the same. This pan is suitably hung or suspended from the water supply tank 1U and a tank 85 which is arranged upon the rear of thev tank 10. The dirty water in the pan 8l is pumped into the tank 85 by means of a suitable pump indi lated at 86 which is mounted upon the' water tank or reservoir 85, said pump being operated by nieans of the eccentric 106 secured to the drive wheel 11.

4In order to' maintain the lower stretch of the traveling mop 68 in sliding contact with the Hoor surface, I provide the curved levers .87 fulcrumed as at 88 upon the frame plates are suitablyconnected, the forward ends of blocks 90 to which the rear ends of the said springs being equipped with the metal hooks 9l are pivotally connected. -These hooks are adapted for engagement with lugs 93 formed upon the rear ends of the arms 92- which are secured to the respective frame plates 56 upon and between which the traveling mop is mounted. Longitudinally disposed lever bars 94 are fulcrumed intermediate of their ends upon the depending brackets 95 secured or formed upon 'the arms 4 the floor surfaceland by their frictional enbrackets 95 and the forward ends of said i bars moved downwardly whereby the rollers 97 bearing against the forwardvends of the -levers 87 rock said levers upon their pivots andinove the rear ends thereof rearwardly and upwardly, thereby expanding the springs 89. The contractile force of these springs exerts a rearward pull upon the mop frame and tends to rock the same in the supporting plates 7 thus .holding the lower stretchof the traveling mop 68 down upon the floor surface in firm constant contact therewith during the movement of the machine. As soon as pressure against the handle bars 13 is released and s aid bars forced downwardly, the upward movement of the forward end of the U 'shaped frame bar l2 cuts ofi' the supply of water to the brushes automatically and elevates the brushes through the medium of the connecting bar 46 to dispose the bristles out of cont'act with the Hoor surface. It will vbe understood that inthe upward movement of the forward interinediate portion of Ythe frame bar 12, the same engages the rod 46 so as to exert an upward pressure against the same and thus elevate the brushes to the position shown in full lines in Fig. Q. Simultaneously with this elevation of the brushes, the forward. en'ds of the bars 9i are raised and the-rollers 97 bearing vagainst the frame plates 56 force said plates upwardly, the lugs 59 on Said plates rocking in the slots 60 of the plates 7, and raising the lower stretch of the traveling mop 68 out of contact with the floor surface. In this elevated position of the mop, the spring clips105 support the casings 61 and prevent downward movement of the roller 67`whicli would engage the lower stretehof the mop68 with the floor surface. The rollers 97 are also moved upwardly along the forward ends of the levers 87, and i the coil springs 89 contract so that'the same offer no resistance to the rocking movement of the mopframe.

From the foregoing description, taken in connection with the accompanying drawings, it is believed that the construction and manner of operation of the several parts of my machinefwill be'clearlyunderstood. -As above stated, in the forward movement of the machine over the floor, a rotary oscillating n'ioveinent .in vopposite directions is imparted to the brushes 19 to which water :is continuously supplied during the forward movement of the machine. wWhen the machine is pulled backwardly in moving the machine from placeto place, the rearward and downward movement of the handles' automatically shuts olf the-water supply and elevates the brushes out of contact with the floor in the manner above explained.

During the scrubbing operation, the lower stretch of the mop 68 is held in close engagementwvith the floor surface by the springs S9, which also operate to maintain the friction wheels 99 in frictional contact with the peripheries of the drive wheels 100. Thus the mop GS is operated, the lower stretch thereof moving forwardly around the tensioning roller 69. F or the purpose of directing the water after it leaves the brush bristles to the central portion of the forward end of the mop, I provide the rubber squeegees 101 which are secured in suitable metal holders`102 suitably mounted upon the longitudinal frame bars 16. These squeegees extend from opposite sides of the central portion of the mop forwardly to points adjacent the outer sides of the respective brushes 19. The squeegees 101 bear closely against the floor surface and direct the water to the center of the mop. As the endless mop 68 moves upwardly and rearwardly over the tensioning roller 6T. the mop becomes saturated with the water which is carried rearwardly to the presser roller 69. This roller is yieldingly held in contact with the upper stretch -of the mop at a point adjacent the periphery of the roller 58 and forwardly of the axis thereof, so that the mop webbing is compressed between the two rollers and the water thus extracted therefrom. rl`his dirty water as before explained, collects in' the pan Sil from which it is discharged into the pan Sl and rally conveyed to the tank S5 by the pump S6. lt will be understood that if desired. the mop and its frame may be bodily removed from the main frame of the machine and employed limlependently of and subsequently to the scrubbing operation. s soon as pressure against the handles 12% is released and said handles forced downwardly, the mop frame is elevated slightly upon the main frame to elevate the lower stretch of the mop out of contact with the floor surface and disengage the peripheries of the wheels 2li) from the friction drive wheels 100, thus breaking the driving connection and stopping the movementof the mop. l preferably provide a hook or latch member indieated at 1021 which is mounted upon the water receiving tank S5 to hold the handles in their lowered position so that after the .hopping operation. the machine may bev freely moved over the floor without again placing the same in operation. 'hen the machine is not in use, the brushes 19 may be elevatedfthe rod 46 being disposed in a substantially vertical position, the hook 46 on the end of said rod being adapted toI be disconnected from the crank arm 48 and engaged with the transverse rod 10T, which is suitably secured to one section of the tary brushes. These brushes may be easily A and quickly removed from the forward ends of the frame bars 16 and when the bristles thereof become greatly worn, any one or more of the bars to which the bristles are afxed may be easily and quickly removed from the body of the brush and a new row of bristles supplied thereto.

The machineas a whole is comparatively light in weight, land may therefore be easily and quickly moved from place to place by the operator with a minimum of labor.

The several part-s entering into the construction of the invention are all of simple form thereby rendering the machine comparatively inexpensive to manufacture, and highly durable in practical use. The parts may also be readily assembled or disassembled by the operator for the purpose of cleaning or repairingthe same.

lVhile I have shown and described the preferred construction and arrangement ot' the several parts employed` it is to be understood that the invention is susceptible of a great many modifications therein and l therefore reserve the privilege of resorting to all such legitimate alterations as may be fairly embodied within the spirit and scope of the appended claims.
